我正在處理另一個人的代碼，當我部署 laravel 應用程序時，登錄頁面可以工作，但是當我輸入測試憑據時，它會拋出此錯誤    Trying to get property 'id' of non-object    in helpers.php line 159    at HandleExceptions->handleError(8, 'Trying to get property \'id\' of non-object', '/var/www/html/first-project/app/Helpers/helpers.php', 159, array('fields' => object(Collection), 'fieldsValues' => object(Collection), 'htmlFields' => array(), 'startSeparator' => '<div style="flex: 50%;max-width: 50%;padding: 0 4px;" class="column">', 'endSeparator' => '</div>', 'field' => object(CustomField), 'dynamicVars' => array('$RANDOM_VARIABLE$' => 'var15931958241638660037ble', '$FIELD_NAME$' => 'phone', '$DISABLED$' => '', '$REQUIRED$' => '"required" => "required",', '$MODEL_NAME_SNAKE$' => 'user', '$FIELD_VALUE$' => '\'+136 226 5660\'', '$INPUT_ARR_SELECTED$' => '+136 226 5660'), 'gf' => object(GeneratorField), 'value' => object(CustomFieldValue)))    in helpers.php line 159實際引用的函數如下function generateCustomField($fields, $fieldsValues = null){    $htmlFields = [];    $startSeparator = '<div style="flex: 50%;max-width: 50%;padding: 0 4px;" class="column">';    $endSeparator = '</div>';    foreach ($fields as $field) {        $dynamicVars = [            '$RANDOM_VARIABLE$' => 'var' . time() . rand() . 'ble',            '$FIELD_NAME$' => $field->name,            '$DISABLED$' => $field->disabled === true ? '"disabled" => "disabled",' : '',            '$REQUIRED$' => $field->required === true ? '"required" => "required",' : '',            '$MODEL_NAME_SNAKE$' => getOnlyClassName($field->custom_field_model),            '$FIELD_VALUE$' => 'null',            '$INPUT_ARR_SELECTED$' => '[]',        ];它在控制器中的用法如下。它在幾乎所有控制器中多次使用，例如在 UserController.php 文件中，我認為這是調用方法。我不太熟悉 Laravel，對于任何菜鳥錯誤提前表示歉意。
